Storage material, for storing electrical energy by reduction or oxidation of an active component, comprises the active component in at least a reduced and/or oxidized form and a reactive framework structure that is capable of chemically integrating at least one form of the active component in the form of a mixed oxide or an alloy into the reactive framework structure during the charging or discharging process. In the case of an oxidic framework structure, said integration can occur by formation of at least one stable mixed oxide of the active component and an oxide from the framework structure. In the case of the metallic framework structure, said integration can occur by forming an alloy of active component and at least one metal of the framework structure.

Electrochemical storage material and electrochemical storage device for storing electrical energy, comprising such a storage material

The substrate-supported anode for a high-temperature fuel cell comprises an at least three-layer anode laminate on a metallic substrate. Each of the layers of the anode laminate comprises yttria-stabilized zirconia and nickel, wherein the mean particle size of the nickel decreases from one layer to the next as the distance from the substrate increases. The last layer of the anode laminate, which is provided for contact with the electrolyte, has a root mean square roughness of less than 4 &#x3bc;m. The overall mean pore size of this layer is typically between 0.3 and 1.5 &#x3bc;m. Starting powders having a bimodal particle size distribution of yttria-stabilized zirconia and nickel-containing powder are used at least for the first and second layers of the anode laminate. The mean particle size of the nickel-containing powder is reduced from one layer to the next, whereby it is advantageously no more than 0.5 &#x3bc;m in the last layer of the anode laminate.
